I heard that when ttc it is good to start taking prenatal vitamins. Before my first pregnancy I had never taken any form of multivitamin but when I took the prenatals that my Dr gave me I couldn't keep them down tried every trick in the book but nothing worked I for a brand of multivitamin that didn't make me sick and stuck with those but it has been 8 years since then and those vitamins have since been discontinued what would be a good alternative to prenatal vitamins when ttc
